Pull Out

So my boyfriend and I had sex the day after I ovulated. We first used a condom then we decided to use the pull out method which I know doesn't work to well. Before he inserted me without a condom I had him clear his tubes by urinatining then we went back to having sex. Without a condom the sex hurt so bad and I believe he may have officially popped my cherry. He never came inside of me. What are my chances of pregnancy?
